### Using Direct CAD Interfaces

Direct CAD Interfaces (DCI) allow you to connect directly to your CAD software. As the CAD file is updated in your CAD software, PC-DMIS reflects the corresponding changes.

Instead of translating CAD data into the internal CAD format of PC-DMIS, the Direct CAD file types are accessed directly. That is, the CAD data of these file types remains in its native format after being imported. Routines native to the CAD type are used for all calculations done on the CAD data. Accessing the CAD data directly eliminates problems that can occur because of translation inaccuracies or limitations.

For detailed information, see the "Direct CAD Interface" documentation.

PC-DMIS supports the use of the following DCIs:

- ACIS

- CATIA 5

- Creo

- Solidworks

- NX

Your LMS license or portlock must have the following options enabled: CATIA V5 DCI, NX DCI, PRO-E DCI, and Solidworks DCI.
